Lily Spring Area Survey

About the Lily Spring Area Survey

The goal of the Lily Spring Area Survey (LSAS) was to monitor the population of high-elevation native plant species within the San Gabriel Mountains, and make scientifically useful comparisons with observations made 30 years ago. This was done by repeating a survey carried out in 1981 by Wayne E. Sawyer in an area around Lily and Little Jimmy Springs, and published in Crossosoma in 1987.

Our field observing began in the spring of 2010, largely on the basis of learning about the survey area. The main part of our survey extended throughout the blooming season of spring-summer-autumn 2011. Some parts of the survey extended into 2012, and this was especially significant for the collection of specimens in support of the survey.
